"a'c1 ims. c1.61-1-7o This invention relates to a vest pack for carrying containers of relatively heavy weight, "and moreparticularly, toja vest pack of the type employed for human transportation of cylinders of tanks of compressed gas' or fluid of underwater breathing apparatus. p i i v i Tanks of underwater breathing equipment containing a; compressed ,fluid, such as air or oxygen, heretofore, have been carried on'the' back'of a person for skin diving by various'types of pack harnesses which are made of a plurality of straps of fabric material and of metal parts. Such harnesses, however, do not provide maximum comfort'tothe wearer, are diflicult to put on and to remove, especially in case of emergency underwater, and fail to distribute ther'elatively heavy weight of the tank evenly over the body of the wearer for providing'maximum freedom of movement underwater and out of the water.
- It is therefore the purpose of the present invention to provide a vest'pack for carrying compressed fluid tanks of underwater breathing apparatus which is adapted to be worn as a 'vest or jacket bya person; which vestipack provides complete comfortby its run body coverage, its
l at'ented May 2, 1961 jacket 12 of body-fitting form having aback or rear-section 14 and a pair of front sections 16 and -18 eachcon- 22, The vest 12 is constructed of any pliable or flexible material, such as fabric, and preferably of Navytype heavy duck' canvas for strength and durability. The frontsections 16 and 18 of the vest are adapted to be sep-' arably connected to each other at the front of the garment by suitable means, such as a slide fastener 24 secured to the front marginal edges thereof for permitting putting the vest-on and off. The vest 12 may bequ ickly and very easily taken off by simply pulling the slide fastener 24 downwardly and thereby disconnecting the frontsections 16 and 18. Art the free edges, as around the neck and arm openings 22 and 20, the vest may be reinforced by strips 26 of fabric sewn or secured thereto for preventing tearing of the material. At the lower edge ofthe waist portion of the vest 12, an elastic band 28 may be provided for snugly fitting on the body of the wearer thereby preventing upward pulling of the vest. The "back section 14 and the front sections 16 and 18 are tailored to a body filtting'form and are thus adapted to be Worn over the upper part of the body of a person.
The vest 12 may also be provided with a pair of side straps or bands 30 on each side thereof, each of which straps 30 is connected at one end, as at 32, to the back section 14 and at the other end is adapted to be passed through a pair of loops or D-rings 34 on'the sides ofth e front sections '16 and 18 in a conventional manner. The vest'12 may thus be adjusted to the size or dimension of the body of the wearer by simply pulling the free end of snug fit, and by its distribution of the tank weight evenly provide a compressed fluid tank vest pack on which the tank is securely held in place thereby preventing the tank from swaying in any direction, ride up or slip sideways, or float around, and which vest pack has many features of maximum comfort and safety.
It is still further the purpose of the present invention to provide at vest pack of the type described which permits easy removal of the tank; is of simple and durable construction, and which is very effective and elficient in use. i
, -A vest pack foricarrying compressed fluid tanks of' .underwater breathing apparatusconstructed in accordance with the present invention comprises a vest of pliable material adapted to be worn over the upper part of the body of a person, and tank holding means secured to said vest on the back thereof for carrying a tank of compressed fluid.
These and other features of the present invention are described in detail below in connection with the accompanying drawing, in which like numerals designate like parts, and in which:
Figurel is a front elevation of a vest pack embodying the present invention;
Figure 2 is a rear elevation of the vest pack of Figure l; and
Figure 3 is a side elevation of the vest pack of Figure 1.
Referring in detail to the drawing, the vest pack for carrying compressed fluid tanks of underwater breathing apparatus illustrated in the drawing as an embodiment of the present invention is indicated generally by the reference numeral. 10, and as shown, comprises a vest or the straps 30 passed through and'around the D-rings 34. Preferably, the front sections 16 and 18 are each'provided with upper and lower pockets 36 and 38, respec tively, which may include downturned flaps 40provided with snap fasteners as at 42, so that the contents of the pockets are prevented from falling therefrom. The lower pockets 38 are each preferably divided into three sections for carrying weights necessaryfor diving. The upper pockets 36, however, may be used for carrying miscella neous items and a holder strap 44 may be provided below the right side pocket 38 for carrying a knife attachment.
As shown in Figures 2 and 3, a cylindrical container; cover or holder 46, also of the same material as the vest 12, is connected to the back section 14 by a pair of sub stantially rectangular panels 48 of fabric extending rearwardly therefrom. The panels 48 are each connected at one end along a longitudinal edge and part of transverse edges to the back section 14 adjacent to thesidesthereof and similarly at the other end to the sides of the container 46; The panels 48 arethe main supports and are arrangedto hold the container 46 firmly. against the back section 14" when thevest 12 is worn on the body of'jthe wearer and a. tank,as indicated at 50, 'iscargiedjthere'jinj thereby "preventing rolling of'the tank 50 sideto side; Also, a pair of upper straps 52 running from the shoulder portions of the back section 14 the top of each side of the tank container 46 and a pair of lower straps 54 connected to the waist portion of the back section 14 and to each side of the bottom of the container 46 prevent the tank from moving longitudinally of the back section 14 especially downwardly, and further reinforce the support of the tank container on the vest 12. The panels 48 may also be reinforced at the edges by strips of fabric, as indicated at 56, sewn thereto.
The cylindrical container 46 is arranged to completely enclose the cylinder or tank of compressed air 50, except at the upper end in which the container 46 is formed with an opening 58 of a lesser diameter than the remaining portion-of the container for permitting the upper end of the. tank 50 to extend above the container 46 and the valve 60 on the upper end of the tank 50 to be disposed above and entirely clear of the container 46. The gas cylinder 50 is supported 'on the bottom end '62 of the container 46 which may .be .provided with a webbing handle 64 forfacilitating holding of the bottom 67. of the container 46 when the tank 59' is removed therefrom. The container 46 is adapted to fit snugly over the tank 50 and to be closed by a lacing 66 passing through grommets or eyelets 68 provided on either side along the edges on centrally split back portion of the container 46, as indicated at 70 in Figures 2 and 3. The split 70 extends from the upper circular edge for substantially'the full ,length of the container '46 and termi nates in a few inches above the container bottom 62 for facilitating insertion or removal of the tank 50 from the container 46.
Attached at the lower back edge of the vest 12, there is 'a pair of D-rings for engaging a crotch strap 74 of fabric formed with a Y-shaped front end 7.6 which is provided with outer snap fastener 78 adapted to engage inner snap fasteners 80 adjacent to the lower edge of the front vest sections 16 and 1 8. The crotch strap 74 may be adjusted in length by pulling the free endof the strap 74 passed around the D-rings 72 for accomodating the wearers of different sizes. The vest 12 may thus be prevented from moving upwardly by the crotch strap 74in addition to the action of the elastic waist band 28.
From the above description of the vest pack of the present invention it is readily seen that this vest pack is extremely compact, light in weight, very strongly constructed with no parts that may corrode upon exposure to salt water and which distributes the tank Weight evenly over the whole chest and stomach areas of the wearer making it exceptionally comfortable.
The present invention has been described in detail above for purposes of illustration only and is not intended to be limited by this description or otherwise, except as defined in the appended claims.
